Description
Technical Field
The invention relates to a device for assisting dust collection in particulate matter treatment before filtration.
Background
The air purifier is used as a device capable of improving air cleanliness, and the purpose of purifying air is achieved by absorbing, decomposing or converting various air pollutants through an internal filtering unit.
The mainstream particulate matter filtering technology of the air purifier is as follows: physical interception (using HEPA) and high-voltage electrostatic dust collection technology, wherein the particle size of the particles and the filtering efficiency are in direct proportion in the two technologies, namely the larger the particle size of the particles is, the better the filtering effect is. In order to improve the capture efficiency of the filter unit for the fine particle pollutants, a coalescing module is usually disposed on the air inlet surface of the dust filter to ensure that the fine particle pollutants in the air entering the dust filter can be coalesced into large particles and thus can be easily captured by the dust filter. However, since the inner space of the air cleaner is limited, the time for the dust-containing air to flow from the coalescing module to the dust filter is very short, and although the fine dust particles are processed by the coalescing module, a certain time is required for the coalescing process of the fine dust particles, so that most of the fine particle pollutants are not completely coalesced into large particles when entering the dust filter and then penetrate through the dust filter, thereby seriously affecting the filtering efficiency of the dust filter and failing to further improve the cleaning effect of the air cleaner.
Problems and disadvantages of the prior art:
1. when air is purified, the particle size of particulate pollutants is too small to be easily captured;
2. physical interception (HEPA) technology increases the filtration level of the filter, increasing wind resistance and cost in order to improve the capture efficiency of small particle size contaminants.
3. The high-voltage electrostatic dust collection technology increases the charging time and the capturing time, reduces the wind speed and increases the volume of the air purifier in order to improve the capturing efficiency of small-particle-size pollutants.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a device for assisting dust collection in particulate matter treatment before filtration.
The invention is realized by the following technical scheme:
a device for processing particles before filtration and assisting dust collection comprises a shell, a device before filtration, a filter and a detection device; the pre-filtration treatment device comprises a positive and negative high-voltage electrode layer, a plurality of electrode wires are arranged on the positive and negative high-voltage electrode layer, and the positive and negative high-voltage electrode layer are arranged at intervals; when air passes through the positive and negative high-voltage electrodes in the pre-filtration treatment device, particles in the air are forced to be charged, and the particles with different electric properties are condensed to increase the particle size and then are filtered by the filter.
Preferably, the detection device is used for detecting an electric signal between the positive and negative high-voltage electrode layers.
Preferably, the electrical signal is a frequency, current, voltage or resistance signal.
Preferably, the distance between the positive and negative high-voltage electrode layers is 2-50 mm.
Preferably, the electrode wires in the positive and negative high voltage electrode layers have the same interval; the interval between the electrode wires in the positive high-voltage electrode layer is the same as or different from the interval between the electrode wires in the negative high-voltage electrode layer.
Preferably, the electrode wires on the positive high voltage electrode layer and the electrode wires on the negative high voltage electrode layer are arranged in a staggered mode.

The invention has the following beneficial effects: under the condition of the same level of filter, the one-time filtering efficiency can be improved; the grade of the filter used can be reduced without reducing the filtering effect, thereby reducing the cost. The wind resistance is reduced after the filter level is reduced, and the noise of the air purifier can be reduced. Test data show that when HEPA of H13 filtering grade is used, the service life of the filter can be prolonged (by 200%), the feedback current control output voltage can control the high-voltage output device in an allowable state interval, and phenomena of detonation, ignition and the like are reduced.
